Background

  • Victim Isaias Valdez was shot and killed on I‑45 on July 17, 2009; police later tied the fatal shot to a high‑powered rifle (something like an AR‑15).
  • Officers surveilled an apartment used by Jonathan Siros and associates; execution of a search warrant recovered two AR‑15 rifles, one purchased by appellant Stephen Siros.
  • Witness Juan Figueredo (a federal arrestee and cooperating witness) implicated Stephen: Figueredo testified that Stephen drove a van that enabled Christopher Garcia to shoot the victim and later boasted about facilitating the shot; Figueredo also testified about payment to Stephen after the killing.
  • Stephen gave a videotaped statement claiming he was driving but was surprised when Garcia produced the rifle and shot the victim.
  • Stephen was indicted for capital murder (alleging remuneration); the jury convicted him of the lesser included offense of murder and sentenced him to 36 years. The First Court of Appeals affirmed; Stephen filed a petition for discretionary review raising eight issues.

Issues

Issue Plaintiff's Argument (Siros) Defendant's Argument (State / Appellate Court) Held
Sufficiency of evidence to convict as a party Evidence insufficient: Siros claims he was unaware Garcia would shoot; appellate court applied Jackson standard incorrectly and factual sufficiency should be considered Evidence (Figueredo’s testimony, Siros’s bragging, Siros driving the van, possession/purchase of AR‑15) cumulatively supports party liability under §7.02 Affirmed: Court applied Jackson standard and held evidence sufficient to support murder conviction as a party
Corroboration of accomplice (Art. 38.14) Figueredo is an accomplice; his testimony lacks independent corroboration tying Siros to murder Non‑accomplice evidence (Siros driving, recovery of AR‑15 bought by Siros, statements at club) tends to connect Siros to the offense; defer to jury when evidence conflicts Affirmed: cumulative non‑accomplice evidence sufficiently corroborated Figueredo’s testimony
Accomplice‑witness instruction (whether Figueredo was accomplice as matter of law) Trial court should have instructed jury that Figueredo was accomplice as a matter of law Evidence was conflicting on Figueredo’s culpability; whether he was an accomplice was a fact question for the jury Affirmed: trial court did not abuse discretion by submitting accomplice status to jury as fact question
Jury charge permitting conviction as principal actor Charge allowed conviction as principal though evidence showed Garcia was shooter; this could lead to non‑unanimous or irrational verdict State argued it prosecuted the party theory; any charge error was harmless because evidence overwhelmingly supported party liability and prosecutor argued party theory Affirmed: even assuming error, any harm was non‑egregious and harmless under Almanza factors
